Bovine Serum Albumin
Bovine serum albumin (BSA) is a globular serum protein of approx. 66.5 kDa. Due to its high stability and its lack of interference in many biological reactions, BSA is widely used in diagnostics test systems. Typical applications include the use as protein calibrator, stabilizer or as a blocking reagent.
BSA is often referred to as "Fraction V", based on the original fractionation of human plasma developed by Edwin Cohn. Primarily developed for human albumin production, the process was later adapted to bovine serum albumin. In modern manufacturing processes, Cohn fractionation is now replaced by a modified, more effective heat shock method, resulting in a BSA of significantly higher degree of purity (> 98%).
SERION Immunologics offers a variety of BSA products especially selected to cover the needs of the diagnostic industry.
All bovine products are sourced from controlled abattoirs and are manufactured in the U.S. All animals receive ante- and post-mortem inspections in order to meet regulatory requirements and are classified as "free from infectious diseases and parasites".
